Individually, stress conditions such as drought, salinity or heat have been the subject of intense research. Though a great deal of knowledge has been advanced, a large array of genes responsive to stresses is still unknown and unstudied. In this team project we would like to study the basic aspect of dehydration and heat stresses related genes and proteins. Five projects deal with the dehydration stress (sub-projects 1, 2, 3, 4 and 5), two with heat stress (sub-projects 6 and 7), and one with pathogen stress (sub-project 5). We will use functional genomics, proteomics, structure bioinformatics and physiological approach to study the specific gene function. The approaches used by the 7 sub-projects are complementary. The ethylene response factors (ERFs) family members that have been functionally characterized are involved in plant responses to biotic or abiotic stresses. Hence, this family seems to be a valuable resource to evaluate in terms of its potential for engineering plant stress tolerance. We have four sub-project want to study ERF family genes, i.e., The function of AtERF4 gene (sub-projects 2) and protein structure of AtERF4 (sub-project 4), the function of At2g20880 in dehydration (sub-projects 1) and the function of At5g61600 in dehydration and pathogen defense (sub-projects 5). This will enhance coherence and cooperation among sub-projects for the common interest. We have never formed such a team strong enough like this one working on a defined biological problem which will strengthen our basic research while has a potential to contribute to agriculture improvement.阿拉伯芥番茄ERF家系缺水熱逆境蛋白質體學病毒防禦Arabidopsis thalianaERF familywater deficitheat stressproteomicspathogen defense
